In 2001, she began a career in broadcasting, hosting a television news magazine, Unzipped, for the new Canadian digital cable network ichannel. The show was cancelled the following year due to financial constraints and questionable content at the network, but Clark continued to work for the network in other capacities. In 2004, she joined Rogers Television as host of a daily talk show in Ottawa.

On June 8, 2002, Clark married Chad Schella, formerly the Director of Player Services for the NHL Ottawa Senators. They have a daughter, Alexandra Charmaine Maureen Schella, born on May 26, 2006 and a son, Charles Roger Dennis Schella, born April 1, 2009. Clark took some time off from television after her daughter's birth, and subsequently joined CPAC, the Canadian parliamentary broadcaster. With CPAC, she has hosted Sunday Sound Off, a political debate and panel discussion show, and Beyond Politics, a talk show where she interviews Canadian politicians in depth about their lives outside of politics.[3]
